BRlCKi-MAC'HINE.

SPECIFICATION forming part of Letters Patent No. 293,596, dated February 12, 1884.

Application filed February 5, 1883. (No model.)

To tu whom, it may concern: n

Be it known that I, ROBERT N. Ross, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Im- 5 provement in Brick-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication,

Figure l is part in side elevation and partinvertical section. Fig. 2 is a front end view. Fig. 3 is avertical section, showing the parts in a different position from that shown in Fig. l. Fig. 4 is a top view. Fig. 5 is a rear i 5 end view. Fig. 6 is a perspectiveview ofthe charger. Fig. 7 is a perspectiveview of the lower plunger, and Fig. 8 is a similar View of one ofthe removableplates which form the faces of the dies of the lower plunger.

My invention relates'to that class of brickmachines wherein two approaching plungers press the clay in the molds; and my invention consists in points of novelty hereinafter fully described and claimed.

v Referring to the drawings, A represents the outer casing. or housing of the machine, and B the driving-pulley, rigidly secured to a shaft, B', journaled in boxes B2, secured to a swinging frame, C, supported on a bolt or rod, C',

A 3o having bearing at one end in one side of the housing A, and at the other end in"V a side plate, D, supported by the base D of the machine.

On the shaft B', between the boxes B2, and

55 rigidly secured thereto, is a friction drivingroller, E, (seeFig. 1,) which bears against V and turns a roller -or wheel, F', on a countershaft, F, journaled in suitable boxes, F2, secured to the side plate, D, andto the housing .io A. (See Figs. 1, 2, 4, and 5.) The frictionroller E can be thrown out of or in contact with the roller F by means of a lever, G, fulcrumed in a frame, G', (see Fig. 1,) and connected at its lower end by means of a rod, H, 45 with the lower end ofan arm, I, pivoted to lugs I 'of the housing, and connectedv by its other end to the lower end of the swinging frame C, the connectionbeing made by means of Va pin, C, in the frame, entering slots I" of the arm. Thus it will be seen that by loper- 5o ating the lever the friction-wheels can be brought into and thrown out of engagement.

Vworking in journal-boxes K2, (see Fig. 5,) and 'the latter being on a shaft, L', journaled in 6o boxes L2. (See Figs. l and 5.)

Connected to one of the spokes or arms of p -the wheel K is an arm, M, the connection beto the upper plunger, Q. by a link, P, (seein/o` Figs. 2 and 3,) and thus it will be seen that as the wheel K is turned this plunger will be iirst raised, as shown in Fig. l, and then compressed, as shown in Fig. 3, and .as the pin K3 works in a slot of the arm, there vwi-ll 75 I be 'a los't motion at each revolution of the wheel, allowing the plunger to remain at rest at short intervals each time it is raised, allowing time for the bricks tobe removed and the molds refilled, as hereinafter described. 8o R represents a c'ounterbalance-weight for sustaining the plunger' during these intervals. (See Figs. l and 3.) u In the same manner that the wheel K is connected to the upper plunger is the wheel L 85 connected to the lower plunger, S, the conneeting --arm being lettered S', the rocking block Si, its supporting-shaft S3, and the link connecting the block with the plunger, Si; but the lower end. of this link has a slot, S5, through 9o which the connecting-bolt passes, the object being to allow the plunger to be raised, after the rocking block has done its work, by means of a lever-arm, U', fulcrumed on a shaft, U,

supported by the housing of the 'machine and 9 5 forward end of the arm engages with the plunger. The other end is operated on by a pin, V', of a wheel, V, on the shaft V2 journalcd in boxes V, secured tothe housing. The wheel V is engaged and driven by a pinion, V, on the counter-shaft F. (See Figs. 4 and 5.) Thus when the block S2 has raised the plunger, as shown in Fig. 3, completing its work, the arm U is operated as described, carrying the lower plunger up as the upper plunger makes its upward movement, the bricks of course being carried up between them, the lower plunger rising to the top of the molds, and thus neither plunger is pulled away from the bricks while in the molds, causing a strong vacuum and frequent injury to the bricks. This I consider a matter of great practical importance, for the power it requires to pull the plungers away from the bricks, owing to the vacuum necessarily created, is very considerable. As soon as the lower plunger has been raised to the necessary height, the pin of the wheel V slips off the lever U, and the 'plunger drops. Vhile the upper plunger is sustained as above described, a charger, \V, makes a forward movement, (see Figs. 1and3,) shoving the bricks that have just been raised from the molds onto a rest, Y, and filling the molds Z with a fresh charge of clay, and then the charger makes a quick backward movement, to get out of the way of the plunger as it makes its descent. rllhe charger is forced for ward by arms T, to which it is connected by a pin, W, working in slots XV of the arms. rlhe arms are rigidly secured to the roel:- shaft U, (to which the lever U is fulcrumed,) and have lower extending ends, W, which are operated on by cams L" and V, striking them from beneath, which are secured, respectively, to the shafts L and V. \Vhen the charger has thus been forced forward, it receives a quick backward movement as soon as the cams leave t-he arms) by an adjustable counter-balance, \Vi, on an arm or lever, NV, rigidly secured to the shaft U. (See Figs. l, 2, and 4.)

XV? (see Fig. 2) is a cushioned post. to receive the counter-balance and stop its descent when the charger has been moved back until its receptacles are beneath the hopper XV,

which holds the clay for filling the charger. (See Fig. 3.) Vhen the charger moves forward the second time, it moves the first pair of bricks from the rest Y (see Fig. l) onto an endless belt, 1, which carries them away, and so on. The belt is driven by a shaft, 2, journaled in the frame,and turned by a chain, 3, connecting it with the shaft F by suitable sprocket-wheels, 4 5. (See Figs. 4 and 5.)

My machine is designed to make twobricks at a time, so there is a pair of molds, and each plunger has a pair of dies', (see Fig. 7,) and the charger a pair of receivingreceptacles (See Fig. (i.) rihe holes S in the lower plunger (see Fig. 7 are to receive the forked end of the lever U.

In order to make different thicknesses of brick, and have a uniform pressure 011 all, I

provide the lower plunger-dies with removable plates Si, (see Figs. 7 and 8,) of different thicknesses.

6 represents strengthening rods or ties connecting the upper part of the machine with the base. (See Figs. 2 and 5.)

I claim as my inventionl. In a blick-machine, the stationary molds Z, in combination with plungers Q and S, connected to blocks N and S2 by links lJ and S, and coupling links or arms M and S and drivewheels K and L, to which the arms are connected, and suitable means for turning the wheels, substantially as shown and described.

2. ln a brick-machine, the charger V, operated in one direction by arms V, pivotcd to the shaft U, and cams L V on the shafts L V2, and in the other direction by a counterbalanec, V", substantially as shown and described, for the purpose set forth.

3. ln a briclrmaehine, the combination ot' d rivingpulley B and friction-roller E, secured to the swinging frame C, and the friet-ionroller brought and held in contact with the driving-roller F by pivotcd arm I, rod l; lever G, and frame G', all substantially as shown and described, for the purpose set forth.
